The present paper deals with the feeding habits and seasonal variation of the feedingintensity of striped mullets along the coast of Xiamen. Samples were taken from XinglinWan, the fish ponds of Houjiang Dai, the ditches of Zhongshan Park and Dongdu Coast,during the period from 1961 to 1962. It was found that the young fishes of striped mullets feed chiefly on zooplanktons,such as copepod Iarvae, Lucifer Gammarus, Trichocerca and Brachinus, and that benthicdiatoms are the main food of both the young and adult fishes in Xinglin Wan. The stomach contents of adult striped mullets ware mainly composed of benthicdiatoms and a little amount of Copepoda, Cladocerans, Ostracods, Protozoans, unocellulargreen algae and blue green algae. Besides, a large amount of organic detritus was alsopresent. Generally the striped mullet changed its feeding habit from zooplankton to ben-thic orgauisms. Seasonal changes of the feeding intensity of striped mullets are closely related to the fluctuation of the water temperature. For instance, when the water temperature was raisedto 26℃ in May 1962,the fullness coefficient of the stomach was found to be 3. 65‰. Inwinter, when the water temperature descended to 10.2℃ in January 1962. the fulless coe-fficient was only 0. 19‰.
